Our robot weighed 30 pounds and it took us three weeks to build it using motors, chains, batteries, sprockets and the armor. The robot had two drive wheels in the back connected by chains to the motors, and an Omni wheel in the front.  As this was our first heavy  bot, we had to learn a lot of new things and made several mistakes too. We did not realise how difficult it was to cut the chains with the limited tools we had for making the motor drives. Even drilling holes through the thick armor was a tough process.

The relatively easier part was wiring the motors, the motor driver, batteries, switches and the radio receiver – as we had previous experiences of wiring arduino-based projects. We named our battle bot- the Black Hole as we hoped it would suck all our competitors. Being a polite, Canadian bot it is a heavy but gentle and friendly robot!
